The collaboration between Wolfram Language and Amazon Braket is propelling quantum computation analysis to unprecedented ranges. By combining Amazon Braket’s superior quantum capabilities and Wolfram’s expansive knowledgebase and accessible symbolic language, customers can now push the boundaries of quantum analysis.

Amazon Braket is a quantum computing service on Amazon Internet Companies (AWS) with the mission of accelerating the event of quantum computing purposes. With Amazon Braket, customers can discover numerous forms of quantum processing models (QPUs), every with its personal bodily implementation. This gives a singular alternative to match totally different applied sciences aspect by aspect. Moreover, Amazon Braket is targeted on envisioning how quantum computing will ultimately match right into a cloud-based IT infrastructure, working alongside different computational sources. Whereas present workloads are experimental, it’s essential for the sphere to start addressing advanced operational points resembling usability, safety, useful resource administration and extra.

The Wolfram Quantum Staff has designed a paclet, known as the Wolfram Quantum Framework and accessible from the Wolfram Language Paclet Repository, to assist in quantum analysis. The Wolfram Quantum Framework is a software program software that allows the event and simulation of quantum algorithms utilizing Wolfram Language. Its key options embrace a library of pre-built quantum features (resembling these for quantum Fourier transforms or Grover’s search algorithm), integration with the Wolfram Cloud and the flexibility to simulate quantum programs symbolically in addition to numerically.

The mixture of Wolfram Language and quantum computation provides an unparalleled alternative to carry out each advanced calculations and quantum duties on QPUs with ease. With the addition of Amazon Braket, this highly effective duo can tackle even essentially the most difficult computational issues. So let’s bounce in and discover the Wolfram Quantum Framework and join it with Amazon Braket by the AWS service.

## The Wolfram Quantum Framework in Motion

To make the most of the Framework paclet, use the next click-to-copy code to put in and cargo it:

Let’s have a look at a couple of examples. A Grover circuit can be utilized to seek out options of a Boolean operate:

A quantum circuit for a Fourier rework of 4-qubits:

A multiplexer circuit, additionally known as a uniformly managed gate:

With the seamless integration between symbolic language and quantum computation supplied within the Framework, customers can carry out a wide range of quantum duties, together with the era of extremely entangled graph states, that are often known as cluster states. These graph states are important for measurement-based quantum computing. Let’s delve into this particular instance for additional insights.

Generate a graph with 4 vertices and 5 edges:

Generate the corresponding quantum state of the produced graph:

It’s value noting the output is a quantum object with some attention-grabbing options, resembling its kind and dimensions.

We’ll then return the system of the earlier state within the computational foundation:

Take a look at if the earlier graph state is entangled:

Take a look at if qubits 1 and 4 are entangled (after tracing out qubits 2 and three):

Repeat the take a look at, however this time, explicitly hint out qubits 2 and three and take a look at the entanglement:

In actual fact, it’s attention-grabbing to notice that the one qubits which can be entangled are these related by way of an edge:

Calculate `QuantumEntanglementMonotone` utilizing totally different measures:

Given a vertex of the graph, we are able to discover the checklist of vertices adjoining to it:

Based mostly on the generated checklist of vertices and their adjacencies, we might want to discover the corresponding stabilizer. This may be obtained by making use of Pauli-X on vertices and Pauli-Z on adjacencies:

Apply this checklist of stabilizers and present that the outcome (i.e. the graph state being reworked by a stabilizer) remains to be the identical as the unique state; this is the reason it’s known as a stabilizer:

Now let’s see the way to generate the graph state utilizing a quantum circuit. In different phrases, the next will design a quantum circuit that transforms a register state right into a desired graph state.

To take action, one can use the built-in graph circuit within the Framework. It will produce a corresponding circuit for producing the identical graph state:

Take a look at the outcome is similar as anticipated (i.e. the circuit performing on the register state produces the specified graph state):

Based mostly on the earlier circuit, we are able to see the `"TensorNetwork``"` of the circuit, which additionally makes use of indices as graph vertices and tensors as cliques:

Moreover, one can create the corresponding multiway graph of the circuit—the place branching occurs with entanglement creation (i.e. in every department, there may be not entanglement and the corresponding quantum state is absolutely separable):

Given the circuit for producing a graph state, let’s now measure every qubit in a particular course on the *xy* aircraft. For qubit 1, the measurement can be carried out alongside the *x* axis (similar to the Pauli-X measurement) after which for the following qubits, we are going to rotate the idea of measurement by π/4 across the *z* axis:

From a computational foundation, we are able to apply Hadamard matrices, which marks the measurement of qubits alongside the *x* axis (i.e. the Pauli-X measurement). Then we apply the *z* rotation gates to rotate the measurement foundation inside the *xy* aircraft by a given angle:

Now let’s discover out what quantum idea predicts to be the likelihood distribution one will get from the earlier circuit. Within the Framework, every time there’s a quantum measurement, the output can be a quantum measurement object:

There are various attention-grabbing options that one can get from a quantum measurement object. For instance, the chances are calculated precisely utilizing statistical functionalities in Wolfram Language:

Or one can straight ask for the corresponding plot:

Moreover, one can simulate measurements for a given variety of pictures. This implies repeating every measurement and counting what final result one will get in every run (which is virtually one realization of the anticipated outcome from a noiseless QPU):

## Amazon Braket and Wolfram Language Mixed

Let’s bounce in and discover the way to make the most of the ability of Amazon Braket’s quantum computing sources utilizing Wolfram Language.

Execute S3 on AWS (if you happen to don’t have an account arrange with S3, you will have to create one):

Execute Amazon Braket on AWS:

At this level, you’ll be related to Amazon Braket and in a position to run quantum algorithms on each simulators and QPUs. You’ll then have to fetch an accessible machine:

On this instance, we are going to use the dataset for an present QPU from IonQ Concord and a simulator named SV1 from Amazon:

Subsequent, we are going to use the generated OpenQASM code to combine with the SV1 simulator. Utilizing `"AWSBraket``"` as a supplier, we are able to then generate the corresponding OpenQASM3 code:

Now we are able to ship the question to the Amazon simulator and our private `"OutputS3Bucket``"`:

Then we are going to generate OpenQASM code for the IonQ machine:

Utilizing this OpenQASM code, we are able to ship a question to the IonQ Concord we picked earlier than:

We’ll then request detailed info on our activity. By reviewing the generated output, we are able to see the standing of the SV1 activity is “COMPLETED”:

We’ll do the identical for the IonQ QPU, however it’s going to take a bit longer. By reviewing the generated output, we are able to see the standing of this activity is “QUEUED”:

The outcomes of the requested updates are saved in S3. We will discover these by finding their directories:

Given the earlier directories, the measurement outcomes could be obtained as follows. It’s value noting that the SV1 listing returns outcomes as counts per `"measurements``"`, whereas IonQ returns outcomes as `"measurementProbabilities``"`. Afterward, we will even calculate SV1 outcomes as `"measurementProbabilities"` for the sake of comparability:

Based mostly on the generated outcomes for each SV1 and IonQ, we are able to then calculate the chances:

We will then chart outcomes for the SV1 simulator (100 pictures), IonQ QPU (100 pictures) and the Wolfram Quantum Framework (precise chances as predicted by quantum idea):
